Is there a way that I can synchronize the calenders on my Powerbook and iMac so that they display the same thing? Under preferences I found that I can do it through a .Mac account, but I don't have a .Mac account. Any way around that?

Yes. You need a web server that support WebDAV, which is required by iCal. My Web Hosting company doesn't support WebDAV, so I had to go with .Mac or do what Flip2gig is doing. I'm on the .Mac trial now but will likely pay the $99 when it's done. To be honest, having everything between my G5 and my iBook synced up is sort of nice. Same bookmarks in Safari, same keychain passwords for web and ftp sites etc.
